Linux Computing Resource

HPC is a distributed memory system. The master nodes, hpc-login1 and hpc-login2, are available for user logins in order to edit, compile, and submit batch jobs to the compute nodes. Hpc-login1 is for 32bit i686 code and hpc-login2 is for 64bit x86_64 code. Each compute node has 2 or 4 cores, at least 32GB of /tmp space, and is connected by a high-performance low-latency Myrinet network.

In addition, 5 nodes with 64GB RAM each are available for large memory jobs.

Due to upgrades, modifications and additions, the following details about CPUs, nodes and resources are subject to change.
